T 0 all whom it may concern.'

Be it known that I, GEORGE HANsLIoK, a citizen of the United` States,residing at Lafayette, in the county of Nicollet and State of Minnesota,have invented certain new and useful Improvements in Loading- Machines;and I do declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to the class of loading and unloading, and moreespecially to those devices having a raised or inclined track o`rplatform and dumping means at the upper end thereof; and the object ofthe invention, broadly speaking, may be said to be to provide improvedmeans actuatedautomatically or manually whereby the windlass is reversedwhen the scoop is dumped and the latter is `retracted to the point ofstarting. In the following specification and claims I have describedthis invention as adapted more particularly for loading manure ontowagons, although it will be clear that dirt, gravel, or other materialcould be brought from a distant point by and in the scoop, carried upthe platform, and dropped into a car or any other suitable receptaclewhich was disposed beneath thc rear end of the framework and platform.

The invention is typically illustrated in the accompanying drawingswherein-L Figure 1 is a side elevation of this machine complete, showingthe scoop in the act of being dumped; Fig. 2 is an elevation from theopposite side, showing the scoop as drawn off the platform; Fig. 3 is aplan view with the upper end of the platform omitted; Fig. 4 is an endelevation; Fig. 5 is a perspective detail showing most of the workingpartsof this machine; Fig. 6 is a perspective detail of the upper end ofthe framework and platform, illustrating the automatic dumping mechanismand its connectio-n with the automatic reversing .mechanism; Fig. 7 isan enlarged sectionaldetail of the driving pulley and clutch, and Fig. 8is an end elevation thereof.

In the drawings a pair of sills 1 support an upright framework 2 whichcarries obliquely disposed converging side strips 8 between which is aninclined plat-form 4 lead ing from the level of the earth upward butterminating short of the upper ends of the strips 3 so as to leavebetween them an opening 5 for dumping purposes. Coacting with thisplatform is a scoop 6 which does not differ essentially from those nowin common use excepting that it has a cross bar 7 adapted to ride ontothe upper edges of the strips 3 when'i the scoop nears their upper ends,and at a proper point just in advance (below) said opening the stripscarry plates 8 on their inner faces whose upper edges 9 are inclinedmore steeply than the upper edges o f the strips so that in effect theyact as cams to lift the extremities of the cross bar on the scoop and totip the latter and cause it to dump through the opening 5 while alsopreventing the scoop itself from falling through that opening.

The scoop-actuating mechanism includes a windlass 10 (preferably madedouble as shown) journaled in the framework, and from one drum of whichleads a rope 11 passing over guide pulleys 12 and 13 and finally over amain pulley 14 at the upper `end of the side bars and branched andconnect'ed as at 15 with the scoo-p; and this may be said to be thedrawing rope. rope 16 leads from the other drum of the windlass over aguide pulley 17, along over the platform and to a distant point where itpasses around? a pulley 18 attached to a. stump or other fixed object,whence it returns to and is attached at 19 to the vback of the scoop;and this may be said to be the retracting rope. Obviously when thewindlass is t-urned in one direction the scoop will be drawn up theincline because of the direction in which the drawing rope is woundaround the windlass, and when the latter is turned in the oppositedirection the retracting rope will draw the scoopV back down the inclineand over the earths surface to a point remote from the machine asA faras the pulley 18 may be disposed. Here the scoop may be lled by hand, orit may be guided on its return movement toward the platform so that itwill automatically scrape up t-he manure or other substance beingtreated, all as will be clearly understood Without further description.

The driving mechanism for the windlass comprises a source of power (agasolene engine G will answer, as indicated in the drawings) belted to apulley 20 which is loose on the main shaft 21 journaled as at 22 in theframework and having a clutch 23 adapted Another to be engaged saidpulley-by means of a lever 24 from which a link 25 leads to a hand lever26 operating over and in conjunction with a toothed segment 27 4securedto one of the sills adjacent the front end of.

the platform, `and it is obvious that an operator standing there ,canmanipulate ,the

lever so as to throw the clutch into or out of engagement and thereforeconnect the main shaft with the source of power at will.

rlhe other end of thevmain shaft is ljour-1 naled as at 30 in a movablebearing conout of meshtherewith ywhen theplateisswung in the Aoppositedirection.-

Journaled ona sub-shaft 35at-thelow'er end ofthe plate 3l (or movablebearing) is a long gearpinion v36 which is in. constant mesh with thegear pinion-33 androt-ated thereby, and the long pinion is moved away.

from the gear wheel34 when the pinion 33 is in mesh therein,andviceversa-,`so that the swinging of the movable bearing31lalternately engages the pinions 33 and 36'with the gear34 on thewindlass and consequently rotates the latter in. opposite direct-ions'.This detail might well be called the shifting or reversing mechanism.vThe manualcontrol for said reversing mechanism consists of a rod 40connected with the upper end of the movable bearing 31 and leadingthence to .an arm 42 at the upper extremity of an upright rock shaft 43mounted in bearings 44 on the frame and having a second arm 45 at itslower end, and this arm is connected by a rod 4G with a hand lever 47which is by preference mounten in the framework adjacent to the segment27 so as to be within reach of the same operator. By moving this handlever in one direction he swings the .movable bearing in one direction,and vice versa; and hence he has control of the reversing mechanismabove described.

yThe automatic control for the reversing mechanism is constructed asfollows: The drawingvrope, near its point of attachment tol thewindlass, has a knot 50 too large to pass through .an eye or loop 5lthrough which the rope passes between the windlass and the pulley l2,this loop being formed at the inner end of a lever 52 pivoted at 53 onthe framework, and to said lever is linked as zit-54 a rod 55 whoseother end is either directly attached to the upper extremity of themovable bearing 3l or connected therewith .through the instrumentalityof the mechanism described below. Therefore when the drawing rope isnearly unwound the knot 50 moves the loop lever 52 which, through theconnection described, causes the movable bearing 3l to on itspivot 32ano reverses the direction .of rotation of the wmdlass automatically.Near its point of "attachment to the'scoop the drawing rope Vhasxanother knot too large to movel through an eye or loop 61 throughwhichv this:ropempasses between the scoop and the pull'ev14', the loop beingcarriedl by'aj lever.

' 62 pivoted atlfincne of the side bars 3, and this lever is connectedby a rod (i4-to the outturned upper end Glof a rock shaft 66 journaled.in bearings 67. o'n anwupright'of the framework-and having a second arm68 at' its lower extremity Iconnectetil ,by-ailink 69 with Ethemovablebearings Blf either di-v rectly-.or through .the instrumentalityof mechanism described zbelow, Therefore whenv -the=scoop reaches ,adumping position the knot: 60l moves the loop lever 62 which, thro-ughtheconne'ctions described, causes the movable bearing 31 teswing on itspivot 32 with= the resultvthat thedirection ,0f-.rotation of the.windlass isvautomatically lreversed;,;i- .i

l-T-he oper-ationof so much-of thy/machine as has been describediisrasfollows: The parts being set upas shown inthe drawings and lthe drivingpullev-20 connected witha source o-fpower such as the gasolene.engine,-for vinstance, when*v the 4operator closes the clutch the powershaft begins to revolve in the direction ofv the arrow. /Thefhand lever47 -will at first-stand upright tohold the reversing mechanismat aneutral point with bothpinions 33: and 36 ,out of en gagement with thegear -wheel 34, so that the power shaft does'y not at first rotate thewindlass at all.r vAssuming now that the scoop lies upon the platform..When the yico operatordraws this hand lever 'forward the I pinion 36 isengaged with the `gear 34-on the windlass and the latter isrotatedinadirection to draw upon the ret-racting rope so that the scoop moves downthe platform and out Iover the ground toward the pulley 1-8. Havingreached that point, unless the operator again throws the reversingmechanism to a neutral position the knot 50 will automatically reverse.the mechanism and the scoop will return tothe platform; and this occurswhere the scoop is used to gather up material such as sand or gravel. Ifhowever, the material being handled is in a distant pile and it isdesired that the scoop remain stationary while it is filled, theoperatcr will throw the reversing mechanism to a neutral position atthis time until the scoop is filled, and then move his hand lever in theopposite direction to engage the pinion 33 with the windlass gear 34,when the windlass will rotate in the other direction and the drawingrope will cause the scoop to be moved over the ground and up theplatform. As it reaches its highest point its cross bar moves over thecams 8 and the scoop is automatically dumped through the the windlasswill commence rotatin opening 5 at the upper end of the platform andinto a wagon or whatever vehicle stands beneath.' Here-agaim if theoperator does not interfere, the other knot 60 will automatically throwthe reversing mechanism s0 that as soon as the scoop has been dumped 4in the wi l again pulley 18 for opposite direction and the scoop bedrawn outward toward the a renewal of the operation.

In connection with the primary or essential features of my inventiondescribed above, I preferably make use of the following amplications'or'refinements in order that the machine may befp'ositive in its actionand that the delays incident to accident may as far as possible beavoided: It sometimes occurs that the nature of the material beinhandled or the manner in which it is loaded into the scoop prevents thelatf ter from dump-ing accurately even 'though' its cross bar travels upthe 'cams under the impulse of the drawing rope. The scoop will dump,but what I mean to say-i's that if the reversing mechanism be actuatedautomatically the scoop must dump quickly or else its direction ofmovement will be reversed before all of the material has been droppedthrough the opening 5. Therefore I preferably employ a bail whose centeris pivoted in eyes 71 beneath the upper ends of the side bars 3 andwhose arms rise alongside the same, have eyes 74, and at their upperextremities hooks 7 5 so shaped that the ends of the cross bar 6 willmove onto them as the scoop passes up the platform, and after engagementtherewith the rear end of the scoop will be raised by the swinging'ofthe arms of the bail. Itis even possible to connect said arms orv one ofthem by means of a link 76 leading from one or both the eyes 74 to theloop-lever 62, and when the knot 60 swings the latter this link willcause the movement of said bail around its pivotso that the scoop willbe dumped in any event. A lock is by preference also employed forholding the movable bearing 3l in either of its extreme positions, foritl will be remembered that at times this machine is subjected to greatstrain and there is considerable possibility thatI the teeth of the gearwheel 34 will disengage those of one or the other of the pinions 33 or36 automatically or accidentally. This lock consists of a bar 80 havingone ,end pivoted at 81 to the movable bearing 31 above its journal 30and the other end pivoted at 82 toa rocking link 83 as best seen in Fig.5.A The lower end of this link 83 is in turn pivoted at 84 to a slidingbar 85 movable in guides 86 on the framework and having its inner endturned downward as at 87 and linked as at 88 to a rock lever 89 whosethrough upper extremity is in turn pivotally con, nected as at 90 withthe rods 55 and 19 r'lo i plast the link and attached as at 96 to somepoint in the framework, so that the link may have the motions yet to bedescribed -as the spring will exert a constant pressure tend-` ing tohold the rocking link in either of its two inclined extreme positions.With this construction of parts, the movement -of either loop lever asautomatically caused by the knot in the rope` is-ilmfediatelycommunicated to the rock lever 89 and by the latter vthe link 88 to thesliding bar 85 which forthwith commences to move; but the movement 'ofthe rock lever is, by reason of the loop 92 in the link 93'between itand the movable bearing 31, more tardily communicated tothe latter, -andby it to the bar 80 which is moved in the oppo-site direction to the bar85, butv at a later time. The `result is that the two extremities 82 and84 o-f the rocking link are moved in opposite' directions. but atdifferent times, although finally the uppermost will move over thelowermost and will carry with it the upper end of the spring 95, so thatonce the lever does position it quicklymoves to its opposite inclinedposition and the 'reversing action is effected rather suddenly'.- By theuse of this lock it is practically impossible for the reversingmechanism to stop on a dead center 105 or neutral point, and when it isdesired that the main shaft shall not drive the windlass in eitherdirect-io-n the operator will be compelled to hold (or to set) the handlever 47 pass an upright or vertical to such position that both themovable bear- I ing 31 and the rocking link 83 will stand strictlyvertical. I consider the employment of this amplification or reinementof advantage to a machine of this character, not

only because the spring-actuated rocking 1,15

link when in either of its extreme inclined positions holds one of thedriving pinions in reliable mesh with the driven gear, but because thereversing-mechanism when set in motion by one of the knots engaging theproper loop-lever is moved by this mechanical detail in such a way thatthe change of direction of rotation is effected quickly. Furthermore, Iconsider it of advantage to make it diicult for the operator to setA thereversing mechanism at a neutral pointrather would I prefer that hemanipulate the other hand lever 26 to open the clutch and disconnect thedriving shaft from the motor, when he desires thatthe operation of thismachine shall cease, for when it is in operation I prefer that the scoopbe mov- 'ing in either' one direction or the other.

All partsl of this machine are of the desired sizes, shapes, proportionsand materials, and modifications and changes may made in the detailswithout departing` trtiin the principle of the invention. In .someinstances, as where a cheaper machine is desired. the auxiliaryscoop-dumping mechanism or the lock for the reversing mechanism may heomitted', orp iaps both might be dispensed with if pre .ii-ed. Assuggested above, this machine is capable of use in a number of ways, andwhere I speak of a scoop throughout the specification it will beunderstood that any device for conveying the material to be handledmight be employed, as the term scoop is used to' conform with thetypical illustration in the drawings.
